Title: Improvements in or relating to closures for bottles and the like
IPC: B65D41/04
Filed: 1951-05-21
Abstract: 696,980. Stoppers. JONES, G. E. May 21, 1952 [May 21; 1951], No. 11818/51. Class 125(iii) In a bottle closure in which a rubber wad is pressed on to the rim by a cap, a non-corrosion disc is interposed between the rubber wad 3 is formed at contents. As shown' the rubber wad 3 is formed at its undersurface with an annular part 6 adapted to engage the rim 4 of the bottle 2 and with a recess for the reception of a bulged disc 5 of hard non- corrosive material such as glass while the upper surface is provided with an annular ridge 7. The disc 5 at its pheripheral edge is as shown slightly clear of the inner edge of the rim 4 of the bottle but when the cap 1 is screwed home the ridge 7 is flattened, the wad 3 compressed against the rim 4 and the disc 5 forced into contact with the inner edge or part of the rim 4 so that the rubber wad 3 is protected from contact with the contents of the bottle. In a modification a countersunk recess is formed around the mouth of the bottle to contain a flat disc of a thickness corresponding to the depth of the recess while the rubber wad is flat and when compressed by the cap presses on both the flat disc and the rim of the bottle.

Title: Improvements in or relating to ratchet feed mechanism
IPC: F16H29/02
Filed: 1944-06-23
Abstract: 587,893. Ratchet gearing. TELEFONAKTIEBOLAGET L. M. ERICSSON. June 23, 1944, No. 11996. Convention date, June 25, 1943. [Class 80 (iii)] [Also in Group XXIX] The liquid flow to a hydraulic press is regulated by a sliding valve rod 12 moved by a yoke 11 and eccentric 10 mounted on a shaft 9. The latter is rotated by two alternatelyacting ratchet means, one of which rotates the shaft 9 at a greater speed than does the other. A ratchet disc 7 fastened on the shaft 9 is rotated by a friction pawl 6 pivoted at 5 to a link 4 which is oscillated about the axis of the shaft 9 by a link 3 connected to an eccentric shaft 2. A ratchet 8 prevents backward (clockwise) rotation of the disc 7. After the disc 7 has been turned through a predetermined angular distance, a cam 19 thereon disengages the pawl 6 by striking a pin 20 thereon. The shaft 9 is then turned by the second ratchet means comprising a disc 13 on the shaft 9, friction ratchet balls 14 in grooves in the disc 13 and an outer disc 15. The latter is oscillated by a link 16 controlled by links 17, 18 from the link 3. The feeding movements of links 17, 18, and consequently the speed of rotation of the shaft 9 may be regulated by adjusting the positions of the pivots 34, 79, of the limbs 3, 16, in slots 41, 71 in the links 4, 17.

Title: Rolling mill
IPC: B21B13/02
Filed: 1964-03-20
Abstract: 1,018,017. Rolling. E. J. HUNTER. 'March 20, 1964, No. 12022/64. Heading B3M. A rolling mill comprises a number of stands in tandem, each being driven from a common source through gearing, and each having work rolls 7 and 8 mounted in blocks 3 and 4, the upper block 4 being urged by tension rods 30, towards the lower block, while the separation of the blocks, and hence the rolls, is determined by screws 15, situated in the upper block and abutting the lower one. The tension rods 30 pass through a supporting base 9 of each stand and are connected, by a cross-piece 29 (Fig. 4, not shown), to a piston 27 of a hydraulic cylinder. The screws 15 at each end of a roll 8 are geared together for manual rotation and are provided with roll pass indicating discs 19 and pointers 20. Should a stand be overloaded, the upper roll with its block is lifted against the pressure exerted by the piston, without damage to the stand. Resetting of the mill screws is unnecessary. The upper roll may, if desired, be lifted by pressurising the under-side of the piston. A four-high arrangement of rolls is possible, the work roll chocks thus moving within the blocks 3 and 4. Lubrication channels 36, 37 and 38 for the roll journals are shown. A low pressure may be applied to the underside of the piston.

Title: Improved method of forming bi-metal patterns especially for use as monoscope targets
Inventor: RAFFAN WILLIAM PATERSON FORSYT
IPC: H01J29/41
Filed: 1957-04-12
Abstract: 858,670. Cathode-ray tubes. RANK-CINTEL Ltd. April 11, 1958 [April 12, 1957], No. 12031/57. Class 39(1). In a process for making a monoscope target the pattern representing a still picture is formed on an insulating support by evaporating a chromium layer 2, Figs. 3, 5, thereon, then covering with a cellulose lacquer layer 3, a photochemical resist layer 4, then placing a stencil 5 having a suitable pattern of apertures on the layer 4 and exposing to ultra violet light, washing away the non exposed soluble parts with water, the exposed parts being less soluble in water and consequently remaining, removing the exposed cellulose lacquer areas by swabbing with polyethyleneglycol or with polyethylenepropyleneglycol (having a molecular weight of about 400), evaporating a layer of gold over the whole surface and then washing in acetone or ethyl alcohol with 10% acetone to remove the remaining islands of resist and cellulose lacquer leaving as shown in Fig. 7 a chromium layer 2 with gold areas 8 the gold areas corresponding to the pattern of apertures in the stencil 5. After further treatment as disclosed in Specification 798,991 the gold and chromium areas exhibit substantial differences in secondary emission ratio appropriate to a still picture which is scanned by an electron beam to generate test picture signals. The chromium layer 2 is evaporated from a tungsten basket on to a glass or quartz plate, preferably to a thickness which is opaque to light emitted from the evaporator and is exposed to air for 24 hours to age it after which a film 0À0005 in. thick of nitrocellulose dissolved in amyl acetate and acetone or nitrocellulose lacquer is applied by ' spinning.' When the cellulose lacquer 3 has hardened the photochemical resist 4, such as bichromated fish glue, is applied by spinning and allowed to dry. When the stencil 5 is laid on 4 the incomplete screen is supported in a vacuum printing frame. The signals derived from the target can also be used for beam position indication. A prior art arrangement is described in which a pattern of carbon or carbonaceous material is deposited on a metal film coated on an insulating base, or on a metal base. This may be done by painting with a liquid compound of benzine soot and turpentine, or printing a pattern in an ink of high carbon content, or photo-mechanical printing in which a light sensitive resist e.g. bichromated fish glue, egg albumen, polyvinyl alcohol or shellac is exposed to light and then the soluble parts removed by washing, the remainder being baked to leave a deposit of carbon of low resistance and low secondary emissivity. The main disadvantage is that the baking oxidises the metal substratum or agglomerates the metal film.

Two sheets A of square shape may carry flanges which can be upturned and stapled inside a collapsable box at the ends thereof.
Patent GB-558248-A (GB)
Title: Improvements in and relating to hydraulic telemotors
IPC: F15B7/00
Filed: 1942-08-27
Abstract: 558,248. Tetemotor apparatus. LAMB, J. A. Aug. 27, 1942, No. 12087. [Class 69 (ii)] In a hydraulic telemotor, the replenishing fluid is placed under pressure each time the byepass valves are opened. Each time the transmitter reaches a mid-position, a cam 7 depresses rods 3 thereby raising the pressure in a channel 14 which communicates with a channel beneath a spring-loaded hollow piston 16 so that this is raised and the liquid super-charged. Further depression of the rods 3 then opens the two byepass valves 12 putting both sides of the telemotor system in communication through passages 30 with the channel 14 and other parts containing the super-charged liquid so making good any leakage or contraction of fluid. Should the pressure in the system be in excess of the supercharged pressure a relief valve 20 in the piston 16 opens allowing liquid to flow into the hollow piston, which is connected through ports 21 and passages 22, 22a with a replenishing tank, till the pressure is reduced to the super-charged pressure. When the transmitter moves from mid position the rods 3 rise relieving the pressure in channel 14 so that the piston 16 descends. Should replenishing fluid have been supplid to the system, the movement of the rods 3 will tend to create a vacuum causing a valve 26 to open and allowing fluid from the replenishing tank to pass through passages 22a, 29 and the valve 26 to make up for this.

Title: Improvements in or relating to illuminating flares
IPC: F42B4/26
Filed: 1944-06-29
Abstract: 579,703. Marine flares. SCHERMULY, C. D., SCHERMULY, A. J., and SCHERMULY, C. June 29, 1944, No. 12363. [Class 9 (ii)] An illuminating flare is adapted to be dropped from an aircraft into water and to be ignited on striking the water, a buoyancy chamber being provided to ensure that the flare floats. The weight 27 and fins 8 stabilize the fall so that the fuze 26 strikes the water and is ignited. The flash from this ignites, in turn the charge 15, the instantaneous fuze 17, the delay fuze 18, the quickmatches 19 and 23, the loop of primed cambric 12, the muslin cover 11 and the flare candle 9. Part of this fuze train is enclosed in the tube 21 made, e.g. of copper. The charge 15 also serves to ignite the quickmatch 33 which, in turn, causes the ignition of the primed cambric disc 28, the quickmatch 32 and the separating charge 30. This charge is carried in an annular recess in the plate 27 and on explosion it causes the cover 3 to be separated from the buoyancy chamber 2 at the weak soft-solder joint 5. The block 27 and spacers 29 fall away from the block 13 fixed to the end of the casing 1 enabling the flare to float by virtue of the buoyancy chamber 2. Ignition of the candle train 15, 17, 18, 19, 23, 12, 11 is well started before the separation of the cover 3. Gases developed by the burning candle 9 force off the weakly attached cover 7.

Abstract: 764,601. Making cans; deforming annular bodies; angular bending. METAL BOX CO., Ltd. March 23, 1955 [April 28, 1954], No. 12377/54. Classes 83 (2) and 83 (4). Apparatus for re-forming can bodies of circular to a non-circular, e.g. rectangular, crosssection comprises a mandrel to receive and reform a can body of circular cross-section substantially to the desired non-circular crosssection, and an anvil co-operating with rotatable rollers respectively to engage the interior and exterior of opposite sides of a re-formed can body to form in each side a permanent bend extending lengthwise of the body. A can body of circular cross-section is fitted manually over a mandrel comprising two reforming elements 3. A pedal then rocks a bell-crank 12 to movea rod 7 axially, which by means of pivoted links 6 moves the elements 3 outwardly to give the can a reactangular cross-section, the elements 3 engaging the narrow sides 4 thereof, the longitudinal seam of the can being positioned so as to fall in the centre of one of the short sides 4. When the elements 3 reach their outer position, the bell crank 12 operates a switch 25 to actuate a pneumatic piston 23 to push forward shaped rollers 16. These engage the exterior of the two wide sides of the can and, as they are moved forward along the can, co-operate with a fixed shaped anvil 1, between the elements 3 of the mandrel, to form panels 27 in the can. In a modification, Fig. 7, the can bodies are pushed, by members 30 on an endless conveyer 31, over reforming mandrel elements 3a, extending from an anvil 1a, which re-shape the can from circular to rectangular cross-section. The can body is then pushed over the anvil 1a and between rotated rolls 16a to form the panels in the sides. The longitudinal bends or panels may be of curved form. The cans may be deformed to oval or other non-circular cross-section.

Abstract: 586,154. Amplitude selective circuits. PHILCO RADIO & TELEVISION CORPORATION. July 30, 1943, No. 12424. Convention date, July 31, 1942. [Classes 40 (iii) and 40 (v)] A circuit for separating synchronizing and picture signals in a television receiver comprises a valve 24, Fig. 1, which may be of beam type, which selects signals having amplitudes lying between certain limits and feeds them to the synchronizing circuits 20, and the characteristic on which the valve 24 operates is controlled in accordance with signal strength to vary both limits of selection. In the examples described, the control is effected at the screen grid of valve 24 which is coupled with the output circuit of valve 9 feeding valve 24 so as to be subject to slow variations transmitted to the control grid of tube 24 and not to rapid variations. The screen load of valve 9 is chosen to peak at a lower frequency than the anode load as described in Specification 530,319. Valve 9 may afford an output which is substantially independent of input, but may be arranged to select a portion of the input of which the magnitude varies with signal strength. In a modification (Fig. 3, not shown), a valve equivalent to valve 9, Fig. 1, has its effective anode and cathode potentials varied in accordance with the slow variations of the input to afford additional control of the tube characteristic.
